6. Press and hold either of the two red trigger buttons on the scanner handle (shown in
Figure 6-2
).
To signify that X-rays are being emitted:
•
The four “X-ray On” warning lamps on the handle illuminate (red),
•
A warning beep sounds,
•
Two beam width warning lasers emit from the scanner face, and
•
The Radiation icon
appears in the Status bar.
7. Move the MINI Z through the scan path (posture shown in
Figure 7-1
and scanning grid pattern in
Figure 7-2
). Move at approximately 6 inches (15cm) per second.
To minimize distortion in the image, hold the front surface of the scanner at a uniform distance and
orientation relative to the surface of the object being scanned (see
Section 7.1, Avoiding
Distortion
).
Scans are automatically saved when they are generated, and appear in the Scan screen as they are
being generated.
8. At the end of the path, release the trigger switch (both switches should be released) to stop
emitting X-rays. (Note: Emissions stop automatically after a maximum of 30 seconds.)To signify
that X-ray emissions have stopped:
•
The four “X-ray On” warning lamps on the handle extinguish,
•
Two warning beeps sound,
•
The two beam width warning lasers extinguish, and
•
The Radiation icon
in the Status bar is hidden.
9. Repeat steps
2
through
7
for multiple scans. (If each new scan starts within 30 seconds of the
previous scan ending, only steps
6
and
7
are required.)
10. View and enhance current images at any time in the tablet
Scan
screen or
Review
screen.
6.1.3
Shutting Down
When shutting down the system, either the tablet or the scanner can be shut down first.
The optimum separation between the scanner face and the surface of the object being
scanned depends on the object being scanned. The scanner can typically return images
when operated from 0 inches (contact with the surface) out to more than18 inches
(46 centimeters) from the surface of the object. For many applications, an optimum distance
is approximately 4 to 6 inches (10 to 15 centimeters).
Tapping the Scan Enable (top) button
again during an active scan emission shuts off
X-ray emissions immediately. This is a safety feature for two-user configurations, allowing
the user holding the tablet to shut down emissions when necessary.
